You might think that borrowing a match upon the street is a simple thing. But any man who has ever tried it will assure you that it is not, and will be prepared to swear on oath to the truth of my experience of the other evening.
I was standing on the corner of the street with a cigar that I wanted to light. I had no match. I waited till a decent, ordinary man came along. Then I said:
"Excuse me, sir, but could you oblige me with the loan of a match？"
"A match？" he said, "why, certainly." Then he unbuttoned his overcoat and put his hand in the pocket of his waistcoat. "I know I have one," he went on, "and I'd almost swear it's in the bottom pocket — or, hold on, though, I guess it may be in the top — just wait till I put these parcels down on the sidewalk."
"Oh, don't trouble," I said. "It's really of no consequence."
"Oh, it's no trouble, I'll have it in a minute; I know there must be one in here somewhere"—he was digging his fingers into his pockets as he spoke — "but you see this isn't the waistcoat that I generally…"
I saw that the man was getting excited about it. "Well, never mind," I protested; "if that isn't the waistcoat that you generally — why, it doesn't matter."
"Hold on, now, hold on!" the man said. "I've got one of the cursed things in here somewhere. I guess it must be in with my watch. No, it's not there either. Wait till I try my coat. If that damned tailor only knew enough to make a pocket so that a man could get at it!"
He was getting pretty well worked up now. He had thrown down his walking-stick and was searching his pockets with his teeth set. "It's that cursed young boy of mine," he exasperated; "this comes of his fooling in my pockets. By God! perhaps I won't warm him up when I get home. Say, I'll bet that it's in my hippocket. You just hold up the tail of my overcoat a second till I…"
"No, no," I protested again,"please don't take all this trouble, it really doesn't matter. I'm sure you needn't take off your overcoat, and oh, pray don't throw away your letters and things in the snow like that, and tear out your pockets by the roots! Please, please don't trample over your overcoat and put your feet through the parcels. I do hate to hear you swearing at your little boy, with that peculiar grumble in your voice. Don't — please don't tear your clothes so savagely."
Suddenly the man gave a grunt of joy, and drew his hand up from inside the lining of his coat.
"I've got it," he cried. "Here you are!" Then he brought it out under the light.
It was a toothpick.
Yielding to the impulse of the moment I pushed him under the wheels of a trolley-car and ran.

How man first learnt to invent words is unknown; in other words, the origin of language is a mystery. All we really know is that man, unlike animals, somehow invented certain sounds to express thoughts and feelings, actions and things, so that they could communicate with each other; and that later they agreed upon certain signs, called letters, which could be combined to stand for those sounds, and which could be written down. Those sounds, whether spoken or written in letters, we call words.
The power of words, then lies in their association with the things they bring up before our minds. Words became filled with meanings for us by experience; and the longer we live, the more certain words recall to us the glad and sad events of our past; and the more we read and learn, the more the number of words that mean something to us increase.
Great writers are those who not only have great thoughts but also express these thoughts in words that appeal powerfully to our minds and emotions. We should therefore learn to choose our words carefully and use them exactly, or they will make our speech silly and impolite.
The origin of language is ______.
A．clearly explained in this passage
B．a matter that can not be or has not been explained or understood
C．a question that was difficult to answer
D．a problem already solved

For sometime past it has been widely accepted that babies--and other creatures--learn to do things because certain acts lead to "rewards"; and there is no reason to doubt that this is true. But it used also to be widely believed that effective rewards, at least in the early stages, had to be directly related to such basic physiological "drives" as thirst or hunger. In other words, a baby would learn if he got food or drink or some sort of physical comfort, no otherwise.
It is now clear that this is not so. Babies will learn to behave in ways that produce re suits in the world with no reward except the successful outcome.
Papousek began his studies by using milk in normal way to "reward' the babies and so teach them to carry out some simple movements, such as turning the head to one side or the other. Then he noticed that a baby who had enough to drink would refuse the milk but would still go on making the learned response with clear signs of pleasure. So he began to study the children's responses in situations where no milk was provided. He quickly found that children as young as four months would learn to turn their heads to right or left if the movement "switched on' a display of lights and indeed that they were capable of learning quite complex turns to bring about this result, for instance, two left or two right, or even to make as many as three turns to one side.
Papousek's light display was placed directly in front of the babies and he made the interesting observation that sometimes they would not turn back to watch the lights closely al though they would "smile and bubble when the display came on. Papousek concluded that it was not primarily the sight of the lights which pleased them, it was the success they were achieving in solving the problem, in mastering the skill, and that there exists a fundamental human urge to make sense of the world and bring it under intentional control.
According to the author, babies learn to do things which ______.
A．will satisfy their curiosity
B．will meet their physical needs
C．are directly related to pleasure
D．will bring them a feeling of success
